Abstract

Apparatus for connection to a metallic structure, the apparatus comprises a transformer rectifier unit operable to output a DC current for cathodic protection of a metallic structure, and a modulator unit connected to receive a DC output from the transformer rectifier unit. The modulator unit is arranged for connection to a metallic structure, and is operable to produce a modulated current which is applied to such a metallic structure when the apparatus is in use, such that the metallic structure is detectable by a wireless locating device. The modulator unit is operable to be controlled remotely.
